Nursing Elites

1. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?

• A. The client can read from 20' what a person with normal vision can read at 30'.
• B. The client can read from 30' what a person with normal vision can read at 20'.
• C. The client can read the entire chart from 30'.
• D. The client can read the chart from 20' with the left eye and from 30' with the right eye.

Correct answer: A

Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.

2. During a health assessment interview, the client tells the nurse that she has some vaginal drainage. The client is concerned that it may indicate a sexually transmitted infection (STI). Which statement should the nurse make to the client?

• A. 'When was your last gynecological checkup?'
• B. 'Have you been engaging in unprotected sexual intercourse?'
• C. Don't worry about the discharge. Some vaginal discharge is normal.'
• D. 'I need some more information about the discharge. What color is it?'

Correct answer: D

Rationale: If the client reports having vaginal drainage and concerns about a possible STI, it is essential for the nurse to gather more information about the discharge. Asking about the color of the discharge helps in determining its characteristics, which can be crucial in identifying potential causes. The color, consistency, odor, and associated symptoms can provide valuable insights into the underlying issue. Statements A and B are relevant questions but not as immediate or specific to addressing the client's concern about the discharge. Statement C dismisses the client's worries and does not encourage further assessment, which is not appropriate in this context.

3. A nurse is preparing to measure a client's calf circumference. The nurse performs this procedure by performing which action?

• A. Placing a tape measure around the widest point of the lower leg
• B. Measuring 2 inches above the knee and placing the tape measure around the client's leg at this point
• C. Measuring 2 inches above the ankle and placing the tape measure around the client's leg at this point
• D. Measuring 2 inches below the patella and placing the tape measure around the client's leg at this point

Correct answer: A

Rationale: To measure a client's calf circumference accurately, a nurse should place a non-stretchable tape measure around the widest point of the lower leg. It is crucial to ensure that the tape measure is positioned at the same number of centimeters down from a specific landmark, such as the patella, on both legs for consistency. Placing the tape measure 2 inches above the knee (Option B), 2 inches above the ankle (Option C), or 2 inches below the patella (Option D) would not provide an accurate measurement of the calf circumference. Therefore, these options are incorrect choices.

4. Which of the following foods is a complete protein?

• A. corn
• B. eggs
• C. peanuts
• D. sunflower seeds

Correct answer: B

Rationale: Eggs are considered a complete protein because they contain all nine essential amino acids required by the human body. In contrast, corn, peanuts, and sunflower seeds are incomplete proteins as they lack one or more essential amino acids. Corn, although a staple food for many cultures, is deficient in the amino acids lysine and tryptophan. Peanuts are low in the amino acid methionine, and sunflower seeds are low in lysine. Therefore, eggs are the correct answer as a complete protein source.

5. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part concentrate and two parts water.
• D. If a portion of one bottle is left for the next feeding, discard it.

Correct answer: B

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is crucial to be cautious when heating bottles in a microwave to prevent milk from becoming superheated. The defrost setting is recommended, and the formula's temperature should always be checked before feeding the baby. Choice B, which advises to discard partially used bottles of refrigerated formula after 24 hours, is also correct. This is important to prevent the introduction of pathogens by the baby into the formula. Choice C, recommending mixing one part formula concentrate with two parts water, is essential for ensuring the correct dilution. Choice D, suggesting to discard any remaining portion of a bottle for the next feeding, is incorrect. It is not necessary to discard the remaining portion if it has been refrigerated promptly and used within a safe time frame. Adding fresh formula to a partially used bottle is not recommended, as it can lead to the growth of pathogens that may be transferred to the new formula.
